If your timesheet has been queried, you will receive notification of this.

Please log in to QWork and click the timesheet that has been queried, you will then see a message explaining why your timesheet has not been approved. 

It may be because your hours you have entered do not agree with the timesheet authoriser or you have forgotten to take off your lunch breaks. 

Once you make the necessary amendments your timesheet authoriser will be emailed notifying them you have made the amendments and will also ask them to approve your timesheet.
